Voltage is an informal term for electric potential difference and is also called electric tension. Voltage is a measure of the energy of electricity, specifically, it is the energy per unit charge. A voltage may represent a source of energy (electromotive force), or it may represent lost or stored energy (potential drop). Voltage is always measured between two points since it is not usually practical to measure the absolute electric potential of a point, and often, a common reference potential will be chosen, such as ground, from which to measure all other voltages. Voltage can be caused by static electric fields, by electric current through a magnetic field, by time-varying magnetic fields, or a combination of all three.
